The Detroit River is short, only 45km, and narrow in places, less than 1km. Around a quarter of the annual $658 billion Canada-US trade crosses over the river. That’s $160 billion worth of goods trucked each year between Detroit in the US state of Michigan and the Canadian city of Windsor in the province of Ontario - the Windsor-Detroit Corridor. There are several types of crossings, but the vast majority of commercial traffic must use the 2.3km Ambassador Bridge (see box). A new bridge was initially prop

New machines from Italian supplier Barin are now being used to help maintain bridges in Thailand.

Proposals to construct the Sunda Strait Bridge are not feasible, according to the Ministry of Energy and Mineral Resources of Indonesia. Safety risks from earthquakes, tsunami, high tides and extreme weather conditions make the project impractical. A US$75.46 million feasibility study was carried out for the project. This pointed out that the bridge is at a high risk from earthquakes and tsunamis due to its vicinity to the Anak Krakatoa volcano.
